The power windows on my 1987 XJ6 III have stopped working but my sunroof still operates. I replaced the relay but that didn't help. The master "child-proof" switch works, as it can be used to prevent opening of the sunroof. However, the neither the front nor rear windows are working. Since replacing the relay didn't work and the master switch seems to be working, any suggestions as to what my process of elimination should be moving forward? The toggle on the front passenger switch is broken but I cannot see why that would cause the other windows not to work. Any ideas?

 

test the rear windows using the rear seat's console switches. if the rear windows work with the rear console switches, the problem is usually the front switches corroded inside. Remove each switch, disassemble them and clean the brass contacts inside them.

 

Thanks for the suggestion, however, the rear seat console switches also do not work. Only the sunroof and lock out switches work.

 

ok, next step is to replace the broken switch with one of the others, preferably one from the rear seat, to confirm the broken driver's switch is not preventing the others from acting.

But the only switch working is the one to the sunroof. All window switches (front and rear) are not working. In other words, all four window switches in the front panel are not working and both window switches in the rear panel are not working. The only switch that works is the one to the sunroof. Can I switch the sunroof switch with one of the non-working window switches (i.e. the driver's switch)?

 

I think all window switches are not working because the driver's window switch is broken, that is what I suspect.

yes, you can use the sunroof switch to replace the broken driver's switch to see if it fixes the issue. All 7 switches are identical.

 

In addition to Jose's suggestion, when you have the switches out get your 12v test light out and see if one of the pin sockets has power. Note the ignition has to be on. If you see no power on any of the leads you know the problem is up stream (towards the fuses) from there. If you do have power at the switch then the problem is probably the switch, or if they are ok, between the switch and the window.

Do you have the s57 wiring diagrams? They will tell you which color wire does what.

Thanks. I have to be out of town for a few days but I'll try that as soon as I return. Where can I get the wiring drawing?

 

Thanks Jose. I have to be out of town for a few days but I'll try this as soon as I get back.

 

if you mean the S57 Wiring Guide, download it free from my website:

Sorry it has taken me so long to get back to this thread, however, I want to thank Jose and Yellow series3 for your suggestions. I was finally able to replace the switches and they are now working.

 

Glad you got them fixed. Feliz Navidad!

 

If anyone on this Forum doesn't have a 12v test light and a multimeter be sure to ask Santa for them (assuming you've been good all year).

I have three multimeters and everytime I use one I have to relearn how to use it..
